SGRAPER-VISE AND BURNISHER.

Application filed July 16, 19,15.

To all whom it may concern.

Be it known that I, JEFFERSON ALLEN, a citizen of the United States, residing at Kennebunk Port, county of York, State of Maine, have invented an Improvement in Scraper-Vises and Burnishers, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to a novel apparatus for burnishing or upsetting the edges of wood scraper blades.

To an unskilled workman the accomplishment of the proper burnishing of a metal blade edge of a wood scraper is difficult and laborious. This apparatus is constructed to provide a simple, manually operable apparatus which efliciently and expeditiously achieves this object. It consists principally of a vise adapted to be removably secured in a fixed position to an edge of an ordinary table or work bench. This vise has clamping jaws which receive and retentively hold the wood scraper in a convenient position. The burnishing meansusually a steel rod-is adapted to be reciprocated across the edge of the scraper. In this novel construction the burnisher is afforded a plurality of mountings by which means it may be operated in planes of different angles to the plane of the scraper so that both straight and beveled scrapers may be properly burnished or upset.

The object of this invention is to provide a novel vise and manually operable burnishing apparatus.

Another object is to provide a burnishing apparatus adapted to burnish both straight and beveled edged instruments.

A. further object is to provide an apparatus adapted to sharpen edged instruments.

Gther objects of the invention will more fully appear from the following description and the accompanying drawings and will be pointed out in the annexed claims.

In the drawings, Figure 1 is a view in side elevation of the vise and burnisher; Fig. 2 is a view in plan of the rear face of the device; Fig. 3 is an enlarged detailed view in elevation of a beveled edged scraper; Fig. t is an enlarged detailed view in elevation of a beveled edged scraper showing in dotted lines the position of the burnisher when in the rear mounting; Fig. 5 is an enlarged detailed view in elevation of a beveled edged Specification of Letters Patent.

scraper and showing in dotted lines the position of the burnisher when in the lower front mounting; Fig. 6 is an enlarged de tailed view in elevation of a straight edged scraper and showing the position of the burnisher when in the upper front mounting.

In the selected embodiment shown, this apparatus comprises a standard 1 adapted preferably to be secured in upright position to a table or other suitable support, as for example, work bench 2. A suitable clamping means which can be easily attached to and detached from the work bench is provided on the standard by means of the arms 3 and 4 adapted to receive the work bench therebetween. The arm- 1 is suitably apertured to receive in threaded engagement therethroughthe set screw 5, of well-known construction, which carries at its inner end a loosely mounted plate 6 which is adapted, upon the turning down of the screw by means of the wings 7, to bear forcibly against the portion of the work bench pre sented thereto and to retain the vise in securely atlixed position thereon. The standard 1 functions also as the fixed member or jaw of the scraper vise of which the jaw 8 is the complement. This jaw 8 carries thereon, and preferably integral therewith, a pair of ears 9 which are adapted to. be pivotally secured to the standard '1 by means of the screws 10. The jaw 8 is thus pivotally mounted upon the standard and is sufficiently held therefrom to permit the facile introduction of a scraper 11. The standard 1 has an aperture therethrough which is adapted to receive in threaded engagement the screw 12 operable, by means of the wings 13, to impinge upon the jaw 55. Upon the turning down of the screw 12, the upper end of the jaw 8 is pressed against the scraper and functions to hold it rigidly in fixed po sition between the standard and the jaw of the vise. The position normally assumed by the scraper is shown in Fig. 1 in which the edge of the scraper projects a short space above the end of the standard.

The burnisher, which in this selected embodiment is a rod 14:, preferably of steel, is shown in Fig. 1 in a plurality of operative positions. The burnisher holder consists of the front arm 15 which, as shown, is secured to the standard 1 by means of the screws 16. This arm projects from the standard preferably at a right angle thereto, while an arm 17 preferably integral with the arm 16, projects in a plane parallel to that of the vertical plane of the standard, as shown in Figs. 1 and 2. The arm 17 has a plurality of apertures 18, adapted to receive the end portion of the rod 14, and thereby hold the rod in operating position. The sides of the apertures 18 are preferably rounded, as shown, in order to attain a better rocking movement of the inserted rod at these points as lever fulcrums. A socket 19 is formed in the arm 3 to afford a further operative mounting for the rod 14-. at the rear of the vise. If the edge is greatly roughened or nicked, a file or similar instrument is first employed to straighten the edges. In this novel construction, two operations are preferably employed to burnish the scraper edges. The first operation is shown in 4 in conjunction with a beveled edged scraper. In this operation, the end of the rod 14 is inserted in the socket 19 of the upper arm 3. The relative shortness of the jaw 8, which as shown in this preferred embodiment extends only part of the length of the scraper, permits the reciprocation of the rod so that its upper portion may be tensionally pressed against the rear portion of the beveled edge, as shown in Fig. l. Upon the completion of this operation, the rod 14: is removed and its end is inserted in the lower aperture of the arm 17. The rod may then assume the position shown in Fig. 1, an enlarged detail of the angular contact of the beveled edge 20 and the rod 14. being shown in Fig. 5. The rod is then manually downwardly pressed and reciprocated along the edge of the scraper until the beveled edge is upset or burnished into the form shown in Fig. 5. In burnishing a straight ed 'ed scraper the first operation is the same. The second operation is illustrated in Fig. 6. In this position the end of the rod 14: is inserted in the upper aperture of the arm 17 as shown in dotted lines in Fig. 1 when the rod may be reciprocated with downward pressure upon the edge of the scraper. While the most efiicient burnishing is produced through the two operations, using the rod consecutively in the rear and front positions, it is obvious that an effective burnishing may be obtained by a single operation.

There is thus provided a simple, manually operable device which it is obvious may be employed not only to burnish various tools but which may be used as a sharpening means for different edged instruments upon Copies of this patent may be obtained for five cents each, by addressing the Commissioner the simple substitution of an abrasive or grinding material for the steel material of the rod 14-. Or, a saw or similar instrument may be rigidly positioned in the vise herein disclosed when it is desired to file the same. This apparatus even in the hands of the unskilled performs its work efliciently and rapidly, has few parts and is of inexpensive and durable construction. Further, the reciprocatoiy movement of the rod while burnishing a particular edge being always held in the same plane, the resultant burnished.

edge is always perfectly formed.

It is to be understood that the construction disclosed herein is illustrative but not restrictive and that the same may be modified within the meaning and scope of the claims which follow.

Having thus described my invention, what I claim as new, and desire to secure by Let ters Patent, is:

1. A tool treating device comprising means able support, said clamping member having means thereon to engage operably said instrumentality whereby the tool edge may be treated from another side of the tool.

A burnishing device comprising a standard, a clamping member pivotally mounted on the standard, and cooperating therewith rigidly to hold an edged instrument, an arm rigidly mounted on said standard, there being means on the arm adapted to engage a burnishing element whereby the edge of said instrument may be burnished in one direction. arms on said standard, means on one of said arms whereby the standard maybe securely clamped to a support introduced between said arms, and means on one of said clamping arms to engage the burnishing element whereby the edge of said instrument may be burnished in the opposite direct-ion.

. In testimony whereof, I have signed my name to this specification. I

JEFFERSON ALLEN.
